Product Description
3kV 10kA Power Station MOV Metal Oxide Varistor (D48×H20mm)
The Power Station MOV Metal Oxide Varistor is an electronic component with variable resistance that changes with applied voltage. Also known as a Voltage-Dependent Resistor (VDR), it features a nonlinear, non-ohmic current-voltage characteristic similar to a diode, but operates bidirectionally.
Key Features
- Constructed from sintered ceramic zinc oxide materials
- Provides optimal circuit protection against excessive transient voltages
- Shunts current away from sensitive components when triggered
- Available in various specifications for different applications
- High energy absorption capacity
Technical Specifications
MOVs are specified according to voltage tolerance range, energy rating in joules, operating voltage, response time, maximum current, and breakdown (clamping) voltage. Energy rating is defined using standardized transients (8/20μs or 10/1000μs).
